  • the internal capacitance value of capacitor unit 15 is calculated by measuring the rate of change of voltage per unit time in charging. At that time, even if capacitor unit 15 is charged with a constant current, the rate of change of voltage is not always constant due to the nonlinearity of the capacitor. That is to say, voltage does not change always linearly. Therefore, in order to calculate more precise rate of change of voltage, the rate of change of voltage, voltage and electric current are measured multiple times repeatedly at predetermined intervals, for example, every one second. From an average value of these measured values, the internal capacitance value and the internal resistance value are calculated (Step (b) in FIG. 3).

  • the corrected internal capacitance value and internal resistance value are compared with the limit resistance values with respect to the internal capacitance values of capacitor unit 15 set at respective temperatures shown in FIG. 6. Thus, it is judged whether or not capacitor unit 15 is deteriorated, i.e., whether or not capacitor unit 15 is in a normal state (Step (f) in FIG. 3).
  • step (d) when it is judged that capacitor unit 15 is in a normal state, the step returns to step (d).
  • the internal capacitance values and the internal resistance values when the temperature of capacitor unit 15 is changed from 0°C to 15°C and to 30°C are shown in FIG. 5A and FIG. 5B, respectively.
  • the limit value is 230 m ⁇ as shown by reference numeral 62;
  • capacitor unit 15 is in a normal state at 0°C and 15°C and in an abnormal state at 30°C.
  • Step (h) in FIG. 3 it is displayed inside a vehicle that capacitor unit 15 is in an abnormal state due to deterioration, and thus the abnormality is notified to a driver.
  • step (d) in FIG. 3 If it is judged that capacitor unit 15 is in a normal state at the time of re-measurement, the step returns to step (d) in FIG. 3 and measurement is continued. Then, it is judged again whether or not the capacitor unit 15 is deteriorated, i.e., whether or not the capacitor unit 15 is in a normal state.
  • the internal resistance value was obtained from the dropped value ⁇ V of voltage right after the interruption.
  • the internal resistance value may be obtained from the increased voltage right after charging is re-started or at the time charging is started.
  • measuring may be carried out by discharging the capacitor unit.
  • the internal resistance value of the capacitor unit is obtained from the increase ⁇ V in voltage due to the interruption of discharging for 80 ms from time T1 to T2.
  • the internal capacitance value and the internal resistance value of the capacitor unit are measured precisely. Furthermore, by comparing the limit values of the internal resistance values at temperatures when the measurement is carried out with the internal resistance values obtained by measuring or correcting, the deterioration of the capacitor unit can be confirmed every time the capacitor unit is charged. Consequently, it is possible to obtain a power supply backup unit with high reliability with respect to temperature change and to obtain a power supply apparatus for a vehicle with a high safety.
  • a power supply apparatus for a vehicle including a power supply backup unit as an auxiliary power supply using a capacitor unit formed of a plurality of capacitors is provided. Even when a battery is in an abnormal state, electric power can be reliably supplied to an electronic controller by the auxiliary power supply. In addition, it is possible to confirm an operation of the power supply backup unit and the deterioration of the capacitor unit every time a vehicle is started to operate. Therefore, a power supply apparatus for a vehicle with high reliability and safety having a power supply backup unit with high reliability is provided. It can be used as a power supply apparatus for a vehicle used for braking a vehicle by an electric control, for example, as a power supply apparatus for a vehicle mounted in hybrid cars or electric vehicles, etc.
